I have used many of the top hp calculators since the early 80’s and the 17bii+ is a very good hp calculator. The build quality is high and this calculator can perform very fast TVM and Amortization and hp Solve calculations; it is much faster than the 12c for example. The 17bii+ is exactly the same size as the hp 32ii+ if you are familiar with that nice calculator. RPN and algebraic entry both work exactly like an hp diehard would expect. You cannot write programs like you can with the scientific hp calculators, but if you want a simple to use high quality financial calculator that isn’t too big, the 17bii+ is perfect.
